Hi.
First of all, a note about your messages. You were saying "may b coz of my
crap language(i dnt thnk so..eh!)": noone will complain on this mailing list
if your English is not perfect (I'm Italian, and most of my mails contain
errors). Nevertheless, using all these "slang" words like "coz", "lil"...
and so on will not help you in receiving a reply from the other folks on the
mailing list.
Regarding your problem, I'm still a bit confused: in the previous mails you
were talking about C (probably using a Borland compiler), now you seem to
talk about C#, which is a completely different story. Can you please provide
us some specific details on your development environment so that someone can
provide you some specific hint to your issue(s)?
Have a nice day
GV
